JanusVM is software that allows you to surf the Internet
without oppression or censorship, while protecting your privacy, security, and identity. It has advanced filtering
capabilities for modifying web page content, managing cookies, controlling access, and removing ads, banners, pop-ups
and other obnoxious Internet junk. JanusVM was designed to be used on Microsoft Windows (2000/XP/2003) and
Linux.

How does it work? JanusVM is powered by VMware, built on the Linux
2.6.14 kernel, and brings together openVPN, Squid, Privoxy, and Tor, to give you a transparent layer of
security and privacy that is compatible with all your TCP based applications. DNS request are also passed through Tor so even your ISP doesn't know what web site
you are looking at. All your web traffic is passed through squid and privoxy to filter out unwanted internet junk & prevents your web browser from leaking information about your computer system.
One of the core components that make this possible is an awesome piece of software called Tor.
Tor is what allows you to re-route your traffic around the internet anonymously.
